IMPROVED MILK-COOLER.

Be it known that I, ABIATHAR FOOT, of Warren, in the county of Litchfield, and State of Connecticut, have invented a new Improvement in Milk-Cooler; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be afull, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

. Figure l, a side view, with a portion of the box removed to show the cooler; Figure 2, avertical longitudinal section; and in Figure 3, a vertical transverse section.

The object ofthis invention is to cool milk in summer and warm it in winter, for the purpose of facilitating the separation of the cream from the milk; and

It consists'in the arrangement of several fiat inclined chutes, one above the other, so that the milk poured upon the upper chute will flow over the surface, and down on to the next below, over its surface, and so on over the several chutes, until it passes Orf from the last. \Vith thisarrangement l combine a case, surrounding the chutes, which may be filled with warm or cold air, or water, as the case may be.

'Io enable others to construct and use nzy improve# ment, I will fully describe the same, as illustrated in the accompanying drawings.

A B G I) are four chutes, arranged inclined one above the other, eaclijeonsisting of an inclined'broad, ilat surface, and, bjy preference, the Aseveral chutes iu- 'cliuing less as they go toward the bottom.

On the first is arranged a mouth, E, into which the -milk is poured, falling into the chute A.

The milk iiows over its surface, running down the conductor F, and flowing through the chute B, thence- -.through the conductor Gto the chute C, thence through the conductor H tothe last chute, I),and thence olf through the outlet I. A

the whole within a case, M, as se'en in ing the chutes is cool. A

If, in cold weather, it is desirable to warm the milk, in order te-permit the separation of the cream before the milkfreezes, I till the chamber with hot water, or otherwise artificially heated, and the milk, in passing through, as before described, will be heated to a sutlicient extent.

To cleanse the cooler after the milk has passed through, pour water vthrough in the same manner as the milk was poured; and I iind it advisable to soald the cooler, by pouring boiling water therethrough.

It will be observed that the extent of cooling de nation of the same, as, if less inclined, the milk will pass more slowly over the surface. I prefer, however, the arrangement I have shown and described.

Having fullydescribed my invention,

1What`I claim as new and useful, and desire to secure by Letters Patent, is-v 'llhe arrangement, Within the case M, ofthe several chutes, A B C D, constructed inclined, and connected so to operate substantially as set forth.
